Here are two of the more logical arguments I have thought of, one for each side. Begging-the-question kind of thoughts.
For the preterists, if Revelation was indeed fulfilled in AD 70 (correct me if I have misunderstood this), then why was it written after the fact? To my understanding so far, the book of Revelation was written in AD 95 ....? I mean, if that is so, what was the point of it being written?
And for the Rapture and Tribulation believers, I have often wondered this: If you believe this and also hold to the traditional view of an upwards Heaven that believing souls go to right after earthly death, then does it not seem weird to go to be with Jesus at the Rapture to escape the Tribulation period, THEN come back to Earth afterward to reign with Him for the 1000 years, THEN have that final Armageddon battle happen where Satan's army is instantly defeated by consuming fire and everyone who ever lived are now judged to go to Heaven or Hell as the lake of fire? So you just end up in upwards Heaven again after you've already been there during the Tribulation time? Why would you ever want to go back to Earth after the first Heaven visit, even for the millennial reign? Now I may have your view here a little wrong in the exact order of events and other details, but it's basically what I remember just sort of being taught, actively or passively, as the mainstream idea all my life.
